I feel like you're missing other commenters' points. The thesis of the article is not "willpower is poorly defined". The thesis is right in the title: "Willpower is a dangerous, old idea that needs to be scrapped". The chosen title and much of the verbiage would be ..very odd if the main thesis were what you claim. The article might successfully argue the much weaker latter thesis, but other commenters are rebutting the main thesis.

My apologies, I wasn't stating his thesis in full. "Poorly defined" in the scientific sense. And to address your concern: a title should not be a thesis, thesis' of articles can be implied, and other commenters to not appear to be discussing the content of this precise article.
